4.8 ON-SCREEN DISPLAY (OSD)
The ST638x OSD macrocell is a CMOS LSI char-
acter generator which enable display of characters
and symbols on the TV screen. The character
rounding function enhances the readability of the
characters. The ST638x OSD receives horizontal
and vertical synchronization signal and outputs
screen information via R, G, B and blanking pins.
The main characteristics of the macrocell are list-
ed below
– Number of display characters: 5 lines by 15 col-
umns.
– Number of character types: 128 characters in
two banks of 64 characters. Only one bank per
screen can be used.
– Character size: Four character heights (18H,
36H, 54H, 72H), two heights are available per
screen, programmable by line.
– Character format: 6 x 9 dots with character
rounding function.
– Character colour: Eight colours available pro-
grammable by word.
– Display position: 64 horizontal positions by 2/
fOSC and 63 vertical positions by 4H
– Word spacing: 64 positions programmable from
2/fOSC to 128/fOSC.
– Line spacing: 63 positions programmable from 4
to 252 H.
– Background: No background, square back-
ground or fringe background programmable by
word.
– Background colour: Two of eight colours availa-
ble programmable by word.
– Display output: Three character data output ter-
minals (R,G,B) and a blank output terminal.
– Display on/off: Display data may be programmed
on or off by word or entire screen. The entire
screen may be blanked.
4.8.1 Format Specification
The entire display can be turned on or off through
the use of the global enable bit or the display may
be selectively turned on or off by word. To turn off
the entire display, the global enable bit (GE)
should be zero. If the global enable is one, the dis-
play is controlled by the word enable bits (WE).
The global enable bit is located in the global ena-
ble register. The word enable bit is located in the
space character preceding the word.
Each line must begin with a format character
which describes the format of that line and of the
first word. This character is not displayed.
A space character defines the format of subse-
quent words. A space character is denoted by a
one in bit 6 in the display RAM. If bit 6 of the dis-
play RAM is a zero, the other six bits define one of
the 64 display characters.
The colour, background and enable can be pro-
grammed by word. This information is encoded in
the space character between words or in the for-
mat character at the beginning of each line. Five
bits define the colour and background of the fol-
lowing word, and determine whether it will be dis-
played or not.
Characters are stored in a 6 x 9 dot format. One
dot is defined vertically as 2H (horizontal lines)
and horizontally as 2/fOSC if the smallest character
size is enabled. There is no space between char-
acters or lines if the vertical space enable (VSE)
and horizontal space enable (HSE) bits are both
zero. This allows the use of special graphics char-
acters.
The normal alphanumeric character set is format-
ted to be 5 x 7 with one empty row at the top and
one at the bottom and one empty column at the
right. If VSE and HSE are both zero, then the
spacing between alphanumeric characters is 1 dot
and the spacing between lines of alphanumeric
characters is 2H.
The character size is programmed by line through
the use of the size bit (S) in the format character
and the global size bits (GS1 and GS2). The verti-
cal spacing enable bit (VSE) located in the format
character controls the spacing between lines. If
this bit is set to one, the spacing between lines is
defined by the vertical spacing register, otherwise
the spacing between lines is 0.
The spacing between words is controlled by the
horizontal space enable bit (HSE) located in the
space character. If this bit is set to one, the spac-
ing between words is defined by the horizontal
spacing register, otherwise the space character
width of 6 dots is the spacing between words.
The formats for the display character, space char-
acter and format character are described hereaf-
ter.
